  • Patent number: 4256304
    Abstract: A baseball suitable for continuous use in a pitching machine comprises a molded, resilient polyurethane foam sphere having a type A-2 shore durometer hardness of less than about eighty to eighty-five. The sphere has a smooth polyurethane surface skin, with the surface of the sphere being provided with a regular pattern comprising a multiplicity of cup-like or hemispherical depressions substantially covering the surface. The baseball has the advantage of durability as well as the advantage of being formed economically in one operation from a homogeneous composition. The cup-like depressions enable the ball to travel greater distances than would be expected for the resilient material, and enhance the accuracy with which the ball can be pitched, bringing the ball substantially within the range of initial performance of a conventional or regulation baseball.
